Specification of Letters Patent.

Patented Sept. 11, 1906.

Application filed June 22, 1905. Serial No. 266,404.

To (LZZ whom it may concern.

Be it known that we, GRANT CAMPION and Mom IVYANT, citizens of theUnited States, and residents of Anderson,in the county of l\ladison andState of Indiana, have made a certain new and useful Invention inGas-Producers; and we declare the following to be a full, clear, andexact description of the same, such as will enable others skilled in theart to which it appertains to make and use the invention, referencebeing had to the accompanying drawings, and to letters and figures ofreference marked thereon, which form a part of this specification.

Figure 1 is a central vertical section on the line 1 1, Fig. 3. Fig. 2is a central vertical section on the line 2 2, Fig. 3. Fig. 3'is atransverse section on the line 3 3, Fig. 2. vFig. 4 is a plan view ofour gas-producer.

The invention relates to apparatus for the manufacture of gas; and itconsists mainly in the improvements upon a gas-producing apparatus orplant shown and described in Letters Patent No. 745,781, dated December1, 1903.

In the accompanying drawings, illustrating the invention, the letter adesignates the circular wall of the gas-producer, which consists ofbrickwork having proper jacketing 0f sheet-iron or steel. This wall orbody portion is supported upon four arcuate foundation-piers b, whichbound the branches f of the crucial-form water-bosh w, which extendsoutward from the circular central basin 1) under the circular wall a tothe shelving-walls c of the exterior or open end portions of saidbranches.

In the construction shown the body-wall a is externally cylindrical, andthe interior surfaces of the upper and lower sections or portions(indicated at 2 and 4) are also cylindrical, the diameter of thelatterportion being less than that of the upper portion. The thickness of thelower portion of the wall'is, however, greater than that of the upperportion, and such thickness is uniform around the section. The uppersection is connected to the lower section by a portion of the wall, theinner surface 3 of which is of conical form, shelving downward andinward from the upper surface 2 to the lower surface 4. Below thisshelving-wall surface the inner surface 4 of the lower section extendsdownward vertically to the arc-form ledges (Z of the foundation-piers b,which project inward a short distance beyond the line of said surface 4and provide arc-form wall-faces 5 of the middle basin 1) of thewater-bosh.

In the basin are secured to its bottom four columns v6, which arepreferably of iron and are located at the corners of a square, eachcolumn or post 6 being separate from, but 0pposite to, one of thearc-form walls of the central basin of the water-bosh. Each column orpost is usually made with a horizontal bottom flange or foot 7, which issecured in the cement of the floor of the basin, and its upper end isprovided with an angular bearingplate 8 to receive and support theangular inner corner of a bearing-shoe e, which rests onthefoundation-ledge d. This shoe 6 is provided with a downward-extendingflange m, which is deep enough to have its lower edge immersed in thewater of the water-bosh, so as to form, in connection with the platingsof the angular bearing 8 and the bridge-plates 9, over the inneropenings of the branches of the water-bosh, a gas-tight joint.

On the shoes e are supported four angular shelving-grates g, whichextend downward and inward from the upper portion of the lowercylindrical surface a short distance below the shelving-surface of thebody-wall. The ridge-line of the angular grate is inclined downward andinward, and from the ridgeline the wings of the grate shelve laterallydownward. The rear margins of the wings, which fit against thecylindrical wall-surface are elliptically curved. Brace-bars a areseated in bearings of the shoes 0 and serve to hold them in relativeposition, thereby also strengthening the columns 6. Between the fourgrates is a crucial opening to the central basin, the four branches ofwhich correspond to the four branches of the water-bosh. The angularinterspace behind each grate forms an air-chamber, which communicateswith a radial passage h through the body-wall, said passage beingprovided at its outer end with a gate 75, in connection with which is apipe p for supplying steam and air, or either, according to requirement.The bottom of this passage 71, is about level with the horizontal planeof the shoe (2.

Between the passages h are provided, through the body-wall, the radialpassages p, the bottoms of which are at a somewhat higher level thanthose of the passages h.

These passages p are also provided with gates and'are designed to servefor inspection of the fuel-bed at the location of the grates and forsuch operations in connection with such bed as may be necessary fromtime to time. These passages p are immediately over the branches of thewater-bosh.

The top if of the chamber within the bodywall is spherically arched andis provided with poke-holes s between the hoppers r.

Each poke-hole is provided with an arming- 1 plate and a lid 11, whichis hinged to said steam-supply pipe.

plate. The arming or seat plate is provided with a threaded seat 2 toreceive a valved union-joint 16, designed to connect with a WVhen thepoke-hole is opened for inspection or working of the fuelbed, steam isturned on to check the escape of gas through said hole, thereby enablingthe work to be attended to Without this very serious obstruction andsaving the gas which would be otherwise wasted.

There are designed tobe four hoppers 7, which are located, respectively,over the grates g. Each hopper is provided with a cover having aninclined marginal flange,

which is designed to fit an inclined flangeseat at the upper end of thehopper-passage. At its lower portion the wall of the hopperpassage,which is rectangular, is slotted through one side for the passage of theslide gate or valve g, which is operated by means of a lever 12, havinga cross-head 13, which is connected to lugs of the slide-gate byparallel rods 14. The gate moves on lateral ways of a bearing-plate 15,to which the hopper is bolted.

The exit-opening, through which the gas is carried to the lines ofdistribution, is indicated at 17.

In this apparatus angular corners and re cesses in the fuel-chamber areavoided above the gratings, and these gratings are designed lowerportion of the fuel-chamber afiords great facility to the operator inworking and removing the pile of ash and cinder under the fuel-bed.

Having described the invention, what we claim, and desire to secure byLetters Patent, is-

1. In a gas-producer, the body-wall, having an interior conicalshelving-surface between an upper cylindrical surface and a lowercylindrical surface, and arc-form foundation-piers supporting saidbody-wall and projecting inward to provide bearing-ledges, substantiallyas specified.

2. In a gas-producer, a body-wall having an interior cylindrical surfacebelow a conical shelving-surface, and four ridged angular grates havingelliptical rear edges fitting said cylindrical surface, substantially asspecified.

3. In a gas-producer, the combination with a body-wall and arc-formledged foundation-piers, of a water-basin having four columns,rectangularly placed opposite to and separate from said piers, andgrateshoes supported by said piers and columns, substantially asspecified.

4. A gas-producer, having four shelving angular gates in its lowerportion, and vertically over each grate, a hopper, substantially asspecified. 1

5. In a gas-producer, the combination with a cylindrical body-wall and acrucialform water-bosh of four arc-form foundationpiers boundin acircular central basin of said water-bos and four columns in saidcentral basin opposite said'piers, substantially as specified.

6. A gas-producer, consisting of a cylinderform body-wall, arc-formpiers supporting the same, a crucial water-bosh having a circularcentral basin bounded by said piers, supporting-columns in said basinopposite said piers, grate-shoes bearing on said piers and columns,shelvin grates on said shoes and hoppers over said grates, substantiallyas specified. l

7. A gas-producer body having a circular interior wall-surfaceconsisting of a conical shelving intermediate portion between its upperand lower cylinder-form portions, in combination with a crucial-formwater-bosh, arc-form foundation-piers, and columns in said water-bosh,four angular shelvinggrates, and four hoppers respectively above saidgrates, substantially as specified.

In testimony whereof we affix our signatures in presence of twowitnesses.
